United, Delta, and Alaska were forced to cancel hundreds of flights after the omicron variant infected employees and crew members.
Extreme weather in some parts of the country also caused further complications.
Expert studies have shown that the risk of severe illness from Covid-19 is reduced by 90 percent or more among people who are fully vaccinated.
While there are breakthrough cases of Covid among people who are vaccinated, they are rare.
In the event of a breakthrough case, victims are highly unlikely to be hospitalized with severe or deadly symptoms from the virus.
Health officials have advised that the Omicron variant is more infectious and could lead to further breakthrough cases.
Yet the spread can be offset by all vaccinated Americans receiving a booster shot.
Current vaccines are expected to protect against severe illness, hospitalizations, and deaths due to infection with the Omicron variant.
With other variants, like Delta, vaccines have remained effective at preventing severe illness, hospitalizations, and death.
Studies have also shown that side effects from the vaccine are extremely rare.

Winter storms throughout the western US have brought rain, snow, and potentially even a rare white Christmas for some.
"Travel will be treacherous, to at time(s) impossible, from the Sierras to the central Rockies this weekend due to whiteout conditions and drifting snow," the National Weather Service warned.
It added that residents could expect "significant mountain snowfall, travel disruptive lowland snow, and rain through the Holiday Weekend."
"Anomalously cold conditions and a barrage of Pacific moisture results in prolonged periods of mountain snow and coastal/valley rain, some of which may fall heavy at times.
And there will be "enough cold air is in place for even metropolitan areas of the Northwest to receive measurable snowfall."
CHRISTMAS CHAOS
On Christmas Eve, United canceled 169 flights, and Delta called off 127, according to FlightAware.
Germany-based Lufthansa said Friday that it was also canceling a dozen long-haul transatlantic flights because of a “massive rise” in sick leave among pilots.
The cancellations on flights to Houston, Boston, and Washington come despite a “large buffer” of additional staff for the period.
Lufthansa said it couldn’t speculate on whether COVID-19 infections or quarantines were responsible because it was not informed about the sort of illness.
Passengers were booked on other flights.
The airline said in a statement that “we planned a very large buffer for the vacation period. But this was not sufficient due to the high rate of people calling in sick.”
“The nationwide spike in omicron cases this week has had a direct impact on our flight crews and the people who run our operation,” United said in a statement to several news outlets."
The airline added: “As a result, we’ve unfortunately had to cancel some flights and are notifying impacted customers in advance of them coming to the airport.”
It said it was working to rebook as many people as possible.
Delta said it canceled flights Friday because of the impact of omicron and the possibility of bad weather after it had “exhausted all options and resources — including rerouting and substitutions of aircraft and crews to cover scheduled flying.”
It said in a statement to several outlets that it was trying to get passengers to their destinations quickly.
PANDEMIC TRAVEL
Air travel across the US is expected to tick back up close to pre-pandemic levels for the holidays.
United CEO Scott Kirby told on Monday that he expected 420,000 customers a day to travel on United flights over the next two weeks.
AAA's holiday travel forecast, released last week, predicted a total of 6.4million people would travel by air between December 23 and January 2.
This is a 184 percent increase over the same period in 2020.
Users took to social media to share their disdain over delayed or canceled flights.
PASSENGER FURY
"@United 'Apologies for inconvenience' [...] do nothing for a woman who cannot see her dying mother. No organization and a complete lack of compassion make [United Airlines] a JOKE," .
"[Asked] the @united airlines flight attendant for advice since the delay was gonna make me miss my connection and he said 'What do you want me to do about that? Good luck' #MerryChristmas," .
A total of 109.5million people are expected to travel over the holidays, according to AAA predictions, despite the growing concern of the new Covid variant.
About 100.1million people are expected to travel by car, while about 2.9million are expected to use other methods like trains or buses.
That's up 33.9 percent over 2020, but still 8.2 percent below pre-pandemic levels of 119.3million travelers in 2019.
